This particular issue was addressed in the Xenomai core, not the I-pipe
patch.

Well, best practice is versioning control and build automation. You can
pull the patch into your local kernel or use the i-pipe kernel git tree
as feed (if you have no own patches). Then you just need
prepare-kernel.sh to refresh the xenomai core.

And building everything can also be automated by scripts or more
advanced systems that also track the source revisions for you. Can be
git, can be something like yocto, buildroot etc.
